To all whom it may concern: upon the thickness of the paper. The forllde it known that I, SAMUEL Gr. Goss, a warding-roll 8 is preferably one 'of the forcitizen of the United States, residing at warding-rolls of any suitable printing press part 0 State of mechanism, which, as it forms no and use- Glencoe, 1n the county of Cook and Illinois, have invented certain new fil Improvements in Mechanism or Producing a Folded Product, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to new and improved mechanism for producing a folded product. As is well known, when a product consisting of a number of sheets is folded centrally, the folded product, especially when it consists of a le number of superconsiderab posed sheets, will have the edges of the inthe fold projecting ner sheets parallel with beyond the edges of the outer sheets, this progression of projection increasing from the outer to the central sheets and from each side. This results, of course, necessarily from the folding together centrally of a number of sheets of the same length or widththat is 'to say, of the same size measured at right angles to the fold. It becomes necessary, therefore, when such pamphlet,'or similar folded product, consists of a number of leaves and whenit is necessary to give particular care to its appearance, that it should be subsequently trimmed in order that the edges parallel to the fold may be even and resent a suitable appearance.

It is the object of my invention to produce a product which will do away with this which will not have to be trimmed after being folded, and also to produce a new and improved mechanism for the production of the same.

In the accompanying drawings Figure l. is an end VlCW diagrammatically illustrating one form of my delivery apparatus; Fig .4. is a side elevation of the same parts shown in Fig. 1 with the. delivery apparatus also indicated diagrammatically; Fig. 3 is a View of the product before folding, particularly as produced by the mechanisms of Figs, 1 and 2 and of course exaggerated in proportions in order to clearly illustrate the nature webs A, B and C such form of printing mechanism.

10, 11 and 12 indicate rotary slitters of the well-known type mounted on a drivenshaft 13. The slitters 10, adjusted longitudinally of the shaft and cooperate with the forwarding-roll 8 to slit longitudinally into several widths or we sections the webs A, B and C passing between them and the forwarding-roll. In the form of device illustrated these slitters are three in number, severing the superposed webs into four sections A, A and 4 These slitters 10, 11 and 12 are so placed upon the shaft 13 that beginning with the section A and going to the right in Fig. 1

the sections progressively but slightly incuts. For inmay also come from any crease in width between the stance,if the superposed sections A were fifteen inches across transversely, the sections A might, for illustration, be fifteen and one-sixteenth, the sections A fifteen and one-eighth, the sections A lifteen and threesiXteenths, in width, measured transversely of the run of the web. These distances, 0 course, will be varied in accordance with the thickness of the superposed webs.

14*15- ably mounted in any we framework of the machine, but in the drawings illustrated only diagrammatically as their construction and operation are so wel understood. as to slope downwardly and diagonally across the press and their function is to turn the paper downward, at the same time bringing face to face, or face opposite. face, the severed sections of the slit'webs, which have theretofore been traveling edge to edge. By means of guide-rollers 18- 1920-2l and adjusting-rollers 2%-2i -24 and 25, all operating in the well-known manner an hence only diagrammatically illustrated, the several sections of the webs are associate and brought together in registry between forwardin -rolls 26 and 27.

28 29 indicate cutting-cylinders, which operate in the. well-known manner to sever the superposed webs transversely and convey them to a the drawings,-8 indicates an ordinary forwardingroll, over which three webs of paper, A, B, an C, are led. The webs B, and C are shown as three in number for convenience. They, of course, may be more or less in number, depending Referring to delivery-cylinder 30, which,

my present invention, is not illustrated. The

in turn delivers the sheets'to fast-running! tapes 3l32 by which the superposed sheets 1 are carried against a stop 33, over folding rollers 34:, between which they are folded by an ordinary reciprocating folding knife 36. From thence they may be delivered to any suitable delivery, as to the ordinary s-fly 37 and slow-moving tapes 38. As has been said, the tape-patlis 8l32 are speeded so as to separate the sheets and give the reciprocating folding knife 36 time to operate. Any other well-known means may be used to separate the sheets, and instead of a reciprocating folding knife any other suitable folding mechanism adapted to fold the sheets betweent-he folding rollers 3a35 may be used.

Fig. 3 represents an end view of the pile of sheets as they might come over the folding rollers 34-35 previous to being folded. From this it will be seen that the several sheets cut from the section A 'are at the bottom, those from A next, those from A", next above, and those from A which are the narrowest of all, at the top. When the pile of sheets is centrally folded in the direction indicated by the arrow in F ig. 8 the edges of the sheets will lie substantially in the same vertical plane. Of course, as has been said, the proportions are exaggerated in Fig. 3 for the purposes of illustration. The sheets may be thus grouped in this sheets of the same Width, superposed above them several more sheets into a pile,

sheets, means for associating on one side to the sheet on sheets of slightly lesser Width than the lower pile but of the same width with each because as long as only three or four sheets. are folded together the fact that they are of the same size is practically negligible,this identity of size caus ing the inner sheets to project more and "more as the pile of course becomes thiclger."

That which I claim as my invention, and desire to secure by Letters Patent, is,

1. In combination, means for forwarding a .web, or wcbs, cutting devices adapted to slit said Webs into a plurality of webs of progressively increasing dimension from one side to the other, means for bringing said webs together with the narrower webs on i one side and the Wider webs upon the other, means for severing said webs transversely to form sheets, and means for piling said having the sheets progressively diminishing in width from one side to the other. 2. In combination, means for forwarding a web or webs, means for slitting said webs into a plurality of webs of slightly increasing width from one side to the other, means for associating said slit webs so that they progressively increase slightly in dimension from one side to the other, means for severing said associated web portions into said sheets in varied slightly from the shcet= the other, and means for folding said sheets centrally.
